This International Standard specifies the nominal dimensions and tolerances of flywheel housings for reciprocating internal combustion engines, in particular those which affect inter-changeability with mating parts.
It applies to reciprocating internal combustion engines except engines for aircraft and passenger cars.
Flywheel housings of size codes 1 to 4 are recommended for commercial vehicles and buses.
